2. LINE VOLTAGE ADJUSTMENTS
PLEASE READ THIS SECTION IN ITS ENTIRETY BEFORE ATTEMPTING TO ADJUST
THE LINE VOLTAGE.
TOOLS REQUIRED:
LARGE FLAT TIP SCREWDRIVER
DIGITAL VOLTMETER
ADJUSTING VOLTAGE
NOTE: The machine must have air pressure at the air gauge or an interlock will prevent it from
powering up.
CAUTION! Working with the electrical services required for the VMC can be extremely hazardous. The electrical power
must be off and steps must be taken to ensure that it will not be turned on while you are working with it. In most cases
this means turning off a circuit breaker in a panel and then locking the panel door. However, if your connection is
different or you are not sure how to do this, check with the appropriate personnel in your organization or otherwise
obtain the necessary help BEFORE you continue.
WARNING! The electrical panel should be closed and the three screws on the door should be secured at all times
except during installation and service. At those times, only qualified electricians should have access to the panel.
When the main circuit breaker is on, there is high voltage throughout the electrical panel (including the circuit
boards and logic circuits) and some components operate at high temperatures. Therefore extreme caution is
required.
1. Hook up the three power lines to the terminal on top of the main switch at upper right of electrical panel and the separate
ground line to the ground bus to the left of the terminals. It is not necessary to be concerned with phase rotation (which
wire is connected to L1, L2, and L3).
